IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 213,510, dated March25, 1879; application filed January 31, 1879.

To all whom it may concern:

Be it known that I, JAMES IRWIN, of Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Vapor-Burners; and I do hereby declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure 1 is an elevation of devices embodying my invention, and Fig. 2is a central longitudinal section of the same.

Like letters refer to like parts wherever they occur.

My invention relates to the construction of vapor-burners, for use withgasoline, benzine, and other light hydrocarbons or easily vaporized andinflammable liquids.

I will now proceed to describe my invention more specifically, so thatothers skilled in the art to which it appertains may apply the same.

In the drawings, (0 indicates the vapor or vaporizing chamber, which issituated, as usual, at the end of the feed-pipe, said feed-pipe bein gfilled with wick or other fibrous material, coarse sand, or brokenglass, or like substance adapted to retard the flow of the liquid to thevaporizing'chamber in the ordinary or any approved manner. When in usethis chamber a occupies substantially a horizontal position, incontradistinction to the vertical position which vapor-burners usuallyoccupy.

1) indicates the deflector, which is united by its stem to thevaporizing-chamber at or near the lower part or base thereof, asindicated by I). This construction causes the heat transmitted by thedeflector to strike the vaporchamber a at its lowest point; consequentlythe chamber is more readily and uniformly heated, and none of the effectof the heat is lost; but in order to increase the effect thevapor-chamber is extended into the deflector by drilling, or otherwise,as shown at 0. At the upper part of vapor-chamber a is the jet-orificed, so placed in order, first, that the gas may issue from the highestpoint of the vaporchamber, whereby the pressure may be more uniform,and, secondly, so that there shall be no overflow before the preliminaryflame or heating cup is supplied. In line with the j etorifice d, and ona line intersecting the vaporchamber a, is a threaded orifice for thereception of the needle-pointed or taper-ended jetregulating screw e.This arrangement of the jet-regulator permits a larger body of metal tobe used at the vapor-chamber, whereby the heat is better retainedwithout materially affecting the symmetry of the burner.

9 indicates the heating-cup, which is placed directly under thevapor-chamber a, and coinmunicates therewith through the threadedorifice f, which orifice also receives a screw, by means of which thecup is held in position.

When the burner is in use, the gasoline or other inflammable liquid usedwill flow from the vapor-chamber a, and. following the screwthreads offwill drip into and supply the cup. The distance the screw is enteredwill, of course, determine the distance the liquid has to travel and theamount of liquid fed to the cup g.

It indicates the spreader, which may be of any approved form, but,preferably, is fanshaped, as shown, and detachably connected to theburner by a threaded peg and nut, as shown, as such construction permitsof its ready removal for cleaning the burner and for other purposes.

The operation of my device is as follows: The liquid to be vaporizedbeing fed in suiticient quantity to the vapor or vaporizing chamher a,the screw f is turned to permit it to flow into the heating-cup g,where, being ignited, it serves to heat the vapor-chamber a and form agas, which escapes by the orifice d and is ignited, impinging on thedeflector. The deflector, becoming heated, transmits the heat to thebase of the vapor-chamber, so that the flame in cup g may then bedispensed with, if desired, though in many instances it will bedesirable to retain the supplemental flame, and when such is the casethe construction described will permit it.

I am aware that a vertical vaporizing-chamber with horizontal deflectorhas heretofore been employed, and do not claim such subjectmatter, forin such construction the feed is dependent upon capillary attractionalone, and the heat from the deflector only reaches the gas-chamber, sothat a uniform and steady flame is not always attainable.

Having thus described my invention, what 3. The combination, in avapor-burner, of the substantially horizontal vaporizing-chamber a, thedeflector b, constructed as specified, the regulating screw e, and thecup g, the whole constructed, combined, and arranged substantially asand for the purpose specified.

In testimony whereof I, the said JAMES IR- WIN, have hereunto set myhand.
